' To all 'whom t may concern.'

lie it lmmvn that 1 Sona HERZOG, a citizen vof the United States, residing at New York, in the county of N ew York and State of New York, have invented certain new and useful Improvements in Bottle- Closures and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and 'use the same.

dispensed.

A further object of this invention is the provision of a valve member inserted in the neck of a bottle or container, a retaining member foi Supporting said valve and an actuating member carried by said valve being detachably carried thereby.

A further object of this invention is the provision of a bottle closure comprising a valve member insertible in the neck of a bottle, a'retaining member for supporting said valve member, said valve member and retaining member having threaded connection with each other and said retaining member being locked to the bottle to avoid accidental displacement in the operation of the valve member.

Further objects will be apparent from the the following specification,- appended claims and drawings, in which,

Figure 1 is a vertical sectional View of parts of a vacuum bottle showing this invention applied thereto,

Fig. 2 is a horizontal sectional view as on the line 2-2 of Fig. 1,

Fig. 3 is a similar view as on the line SB of Fig. 1,

Fig. 4 is a side elevation yof a retaining member,

Fig. 5 is a side elevation of the valve member removed,

Fig. 6 is a vertical sectional view of another form of supporting means,

Fig. 7 is a horizontal sectional view as on the line 7 7 of Fig. 6,

Fig. 8 is a similar view as on the line 8 8 of Fig. 6, and

Fig. 9 is a perspective view of a slightly modified form 0f valve member.

This invention provides for the formation of a bottle closure in which a valve seat is formed in the neck of the bottle or other container, and a valve is movably carried in the neck of said container to permit its being seated to close the passage through the neck of the bottle or said valve may be unseated upon actuation of manipulating means carried by said valve eXteriorly of said bottle. v

Referring to the drawings, in which the several parts are clearly shown, 10 indicates'V the casing of a vacuum bottle having the removable intermediate section 11 to permit insertion of the doubled wall container 12 within the casing 10 and this intermediate section is threaded as at 13 to receive the cap member 14. The sleeve 15, having theV threaded enlargement 17 formed thereon, is insertible in the threaded section k13, where the gasket 18 or other sealing means, may be interposed between the upper extremity of the section 11 and this sleeve. The sleeve k15 has an inwardly directed flange 19 formed therein and the sleeve is recessed as at 20 to receive the packing 21 which lies under the flange 19, so that when the section 1l is attached within the shell 10, the packing 21A forms a seal against the upper edge of the container 12. The upper face of the flange 19 forms a valve` seat against which a washer 22 carried by the valve member 23 presses in seated position, to effectively seal the passage through the neck of the bottle.

The upper edge of the sleeve 15 is internally -threaded as at 24 to receive the retaining ring or cap 25 on which the overhanging flange 26 is formed to compress the washer 27 between the flange 26 and upper edge of the sleeve 15, to thereby seal the passage between these members.

The valve 23 comprises the diaphragm which normally overlies the opening in the neck of the bottle and thisfvalve has the depending guide 28 formed thereon, in which the passages 29 are formed and above this diaphragm is a Wall 30, in which the openings 31 are formed which communicate with an interior chamber 32 and this chamber has which aav'a'sher 56 is placed, so that as the stem 1s rotated in one direction, this Washer connuunication with the exterior of the bottle as through a passage 33. The passage 33 is formed through a stem 34 on which the threads 35 are formed and these threads are of relatively large proportions, being out to avconsiderable pitch, as by using double threads thereabout, sothat quick action in the movement of the valve may be had upon rotation of said stem. In the formationl oi?` the stem 34, a shoulder 55 ris formed upon G'for1ns a seal with the lo-Wer face of the head to prevent the passa-ge of 'liquid about the-same. The threads 35- engage the interiorly threaded opening- 36 in the head 25 andthe thread-s 35 are'cut in opposite direction to lthe external threads on the head 25,-' so* that when the head 25l is locked inthe upper-edge-of theV sleeve 16, manipulation ofthevalvestem 34 does not tend' to loosen theloc'ked relationof the head. rllhe stem rising-abovelthe head2?) is reduced as at 37 has the' pins 31S formed thereon topermit 'said 'val-ve stem being operated as by a removable actuating member 39, vvhichhas the t'slot's 40v formed therein to permit the vertical portions-oi said slots p'assingover thelugs 3S when the actuating member is applied, after which said actuating member may be moved Vin either direction as to cause theliugs- 38 toenter either of the branches ofsaid slots when it isdesired to move the valve stem in either direction, as toy open or close the' passage. The dliaphragn'r Q3 Willfbe of less diameter than the internal diame'tero'l the sleeve 15 above the iange-` valve havingthe depending guide formed thereonyi-n' which the: passages 46 are cut arid/this valve is carried by 47 which depends from acage construction 48 carri-'ed centrally Within the cap memberL 49' which has its overhanging edges threaded-v asat' 50v to operate on' the Ythread '5:1 formed oir-the eX'terior" Wall ioi' i thel bottle' neck. Inf this form,- the sereni tlireaded connection be# means for the valve member as it is clearly seen that the valve may be seated t0 close the passage upon manipulation of ther cap in one direction, or the valve may be un# seated to permit vdischarge of the contents of theV bottle upon reverse movement of the cap.v 'Y' Fig. 9 showsavalve member'cof slightly modified construction in'which 52 indicates the diaphragm having the lugs 53 formed thereon, and depend'ingfrom: thisy diaphragm t is the guide comprising the Wings 54 vWhich may be radially `disposed about a' common center.- Y Y i As shown in Fig. 1, the sleeve 15 may be made-01E metal or o'f'vitreous' material' when used vconnection. With vacuumv bottles and itis evidentv in vievvoi the foregoing, that numerous other .modifications may be made Without departing Yfrom the spirit of .4 this invention, vas the drawings aresubmitted for illustrative purposes only, It is also thougdit that the operation of the severalparts is clear invieW of the foregoing and that further description is unnecessary.

Having thus described' my invention, 1 claim Abottl-eclosure of the class described comprising in combination,- a container having a valve chamber formed' in the neck thereof,Vv
